I never play any Beatmania game and I have no idea who these girls are. But I heard that these figures were sold like hot cake and their price on ebay/yahoo were going like crazy.

Konami had released these Iroha and Lilina before. These two are actually the alternative color edition. For those who couldn’t get the original color version couple years ago and don’t want to pay for the high price on ebay. Maybe you can get this set instead if you don’t mind alternative color.
